1. A method for forming an imaging member having a patterned surface in the outer layer, comprising:

  • providing a mold for imprinting, wherein the mold comprises a pattern on one face of the mold, the pattern comprising an array of periodically ordered protrusions or indentations and wherein the step of providing the mold for imprinting further comprisesink-jet printing a nano- or micron-scale pattern onto a substrate to create a master pattern,applying a flexible material onto the master mold,curing the flexible material onto the master pattern to form the mold,removing the master pattern to produce a flexible mold;

    providing an imaging member comprising a substrate and disposed thereover the substrate a soft outer layer coating for being imprinted;

    applying one or more release agents onto the mold prior to imprinting the outer layer coating;

    pressing the patterned face of the mold and the outer layer coating of the imaging member together in a manner such that the pattern structure of the mold is replicated onto the outer layer coating; and

    hardening the outer layer coating to form a patterned structure on an outer surface of the imaging member.
